This invention relates to a new kind of car byway of example, in theaccompanying dumper in loop-shape for emptying cars. drawings in whichThe improved loop-shaped car dumper Fig. 1 shows in elevation a cardumper works without driving mechanism and the having a regulating chainarranged above 55 cars come out of the device at approxithe entrance andexit.

The cars comeautomatically into confollowing the one the other cause a distact withthe regulating chain 11, owing to placement of the chain of carsstanding on the inclined track, this chain reducing the the loop-shapedtrackway so that one or speed of the cars and conducting the same 15more cars are forced out of the loop.

I claim Anembodiment of the invention is shown, 1. A car-dumper for emptying cars,comprising a track way curved first in down Ward direction and then inupward direction and terminating at the height of the entrance, and toprails on this track Way for holding the cars in the dumper, the carsstanding in equilibrium on the curved track way in a row the buffersbeing in contact.

2. A car-dumper for emptying cars, comprising a track Way curved firstin down- W Ward direction and then in upward direction and terminatingat the height of the entrance, and top rails on this track Way forholding the cars in the dumper, the cars standing in equilibrium on thetrack Way in a row the buffers being in contact, and a regulating chainconducted at car height over the entrance and exit.

In testimony whereof I aflix my signature.
